[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] Reference Figure 1-4 This invention provides a wastewater treatment device for sea cucumber industrial farming, comprising:

[0030] First sewage treatment tank 1, a partition plate 2 is provided inside the first sewage treatment tank 1, and the partition plate 2 is horizontally fixed inside the first sewage treatment tank;

[0031] The first filter mechanism is provided with a through groove 3 on the partition plate 2;

[0032] A conveying mechanism is provided at the bottom of the first sewage treatment tank 1. A sewage outlet 4 is provided on one side of the first sewage treatment tank 1. The output end of the conveying mechanism is provided in correspondence with the sewage outlet 4. A sludge collection tank 5 is provided at the bottom of the first sewage treatment tank 1.

[0033] The second filtration mechanism includes a second sewage treatment tank 6 located on one side of the first sewage treatment tank 1, and a drain hole 7 located on the other side of the first sewage treatment tank 1. The drain hole 7 is located below the partition plate 2 and is correspondingly arranged with the top of the second sewage treatment tank 6. A sealing mechanism is provided on the outer wall of the first sewage treatment tank 1, and the sealing mechanism is correspondingly arranged with the drain hole 7. Several filter components are detachably connected at equal intervals to the second sewage treatment tank 6.

[0034] Among them, the sewage outlet 4 is hinged with a box door 8.

[0035] In use, wastewater enters the first wastewater treatment tank 1, and flocculant is added at the same time. The wastewater is filtered through the first filtration mechanism. The particulate matter in the wastewater aggregates and settles under the action of flocculant. Then, the supernatant of the settled wastewater is discharged into the second wastewater treatment tank 6 through the drain hole 7 by the closed mechanism. The sludge is discharged into the sludge collection tank 5 through the sewage outlet 4 by the conveying mechanism. The supernatant is finally filtered through the filtration components in the second wastewater treatment tank 6 and finally discharged through the drain valve on the second wastewater treatment tank 6.

[0036] The scheme is further optimized. The first filtration mechanism includes two positioning sleeves 9. A threaded rod 10 is fixedly connected to the positioning sleeve 9. The two positioning sleeves 9 are rotatably connected to the inner wall of the through groove 3 through the threaded rod 10. A positioning nut 11 is threadedly connected to the threaded rod 10. A first filter screen plate 12 is slidably connected inside the positioning sleeve 9. A threaded hole is opened on the positioning sleeve 9. A positioning screw 13 is threadedly connected inside the threaded hole. The positioning screw 13 is limited and engaged with the first filter screen plate 12. A slide rail 14 is vertically fixedly connected inside the first filtration pool. A slider 15 is slidably connected to the slide rail 14. Both first filter screen plates 12 are hinged to the slider 15.

[0037] When in use, the positioning screws 13 and positioning nuts 11 can be loosened to adjust the included angle between the two first filter screens 12, and then they can be fixed. The first filter screens 12 are V-shaped to facilitate the passage of sewage. After the sewage is filtered, the two first filter screens 12 can be loosened. After the two first filter screens 12 are flattened, the debris on the top surface of the two first filter screens 12 can be cleaned to achieve preliminary impurity filtration.

[0038] Further optimizing the design, a groove 16 is horizontally formed at the bottom of the first sewage treatment tank 1. The groove 16 has an arc-shaped cross-section. A first drive motor 17 is fixedly connected to the inner wall of the first sewage treatment tank 1. A screw 18 is fixedly connected to the output shaft of the first drive motor 17. The screw 18 is adapted to the groove 16, and the end of the screw 18 away from the first drive motor 17 is correspondingly set with the sewage outlet 4. The edge of the groove 16 is passivated with respect to the bottom surface of the first sewage treatment tank 1, so that the sludge settled in the first sewage treatment tank 1 can enter the groove 16 and be transported out of the first sewage treatment tank 1 by the screw 18. At the same time, an inclined surface can be set on the bottom surface of the first sewage treatment tank 1 to facilitate the sludge transport. The screw 18 can be supported by a support base, and a clearance groove needs to be set to avoid obstructing the sludge discharge. A sealing ring is set on the tank door 8 to improve the sealing effect between the tank door 8 and the sewage outlet 4.

[0039] The scheme is further optimized. The sealing mechanism includes a sealing perforated plate 19, and a second filter screen plate 20 is provided in the drainage hole 7. The sealing perforated plate 19 and the second filter screen plate 20 are correspondingly arranged, and the filter holes on the second filter screen plate 20 are misaligned with the filter holes on the sealing perforated plate 19. Fixing blocks 21 are fixedly connected to both ends of the sealing perforated plate 19. A pad plate 22 is fixedly connected to the top of the first sewage treatment tank 1. The fixing block 21 at the top of the sealing perforated plate 19 is slidably connected to the bottom of the pad plate 22. The fixing block 21 at the bottom of the sealing perforated plate 19 is slidably connected to the side wall of the first sewage treatment tank 1. An electric telescopic rod 23 is fixedly connected to the bottom of the pad plate 22. The output shaft of the electric telescopic rod 23 is fixedly connected to the fixing block 21 at the top of the sealing perforated plate 19.

[0040] After a certain period of sedimentation, the wastewater at the bottom of the partition plate 2 is discharged into the second wastewater treatment tank 6 through the drain hole 7. The filter membrane of the second wastewater treatment tank 6 is set at a certain angle, so that the wastewater directly washes the filter membrane, washing off the impurities on the filter membrane and preventing the filter membrane from becoming clogged. The filter holes on the closed perforated plate 19 and the second filter screen plate 20 are misaligned. When they are aligned, the drain hole 7 can be blocked. By controlling the electric telescopic rod 23, the closed perforated plate 19 is tilted at a certain angle. At this time, the filter holes on the two perforated plates are separated, and the wastewater in the first wastewater treatment tank 1 is discharged into the second wastewater treatment tank 6 through the filter holes on it. At the same time, the arrangement of the two perforated plates can perform secondary filtration on the wastewater in the first wastewater treatment tank 1, preventing larger impurities from falling onto the filter membrane and affecting the filtration effect of the filter membrane.

[0041] The solution is further optimized so that the filter assembly includes several layers of filter membranes, which are fixed on the fixed frame 24. The fixed frame 24 is detachably connected to the second sewage treatment tank 6 through the connecting assembly, and the filter membranes are set at an angle to the bottom of the second sewage treatment tank 6.

[0042] Further optimizing the design, the connecting components include a mounting block 25 fixedly connected to the fixed frame 24. The mounting block 25 has a stepped groove 26, within which a limiting rod 27 is slidably connected. A limiting groove 28 is formed on the inner wall of the first sewage treatment tank 1, with the limiting rod 27 engaging with the limiting groove 28. A spring 29 is fitted onto the limiting rod 27, with one end fixedly connected to the inner wall of the stepped groove 26 and the other end fixedly connected to the limiting rod 27. Furthermore, to facilitate the removal of the limiting rod 27 from the limiting groove 28, a shim can be fixed to the limiting rod 27. The distance between the shim and the limiting rod 27 needs to be greater than the depth of the limiting groove 28, thus facilitating the removal of the limiting rod 27. Under the action of spring 29, the limiting rod 27 can always be inserted into the limiting groove 28. The limiting groove 28 on the second sewage treatment tank 6 is provided in two rows, and the two rows of limiting grooves 28 are staggered, so that the number, spacing and tilt angle of the filter membrane can be adjusted. The filter membrane is tilted to facilitate the passage of sewage.

[0043] In a further optimized design, guide grooves are symmetrically provided on the slide rail 14, and guide blocks are symmetrically fixedly connected to the slider 15. The guide grooves and guide blocks slide in cooperation. (The guide grooves and guide blocks are not shown in the figure.) The slider 15 is limited by the guide grooves and guide blocks, ensuring that the slider 15 can only slide along the slide rail 14.

[0044] Further optimization of the scheme: the bottom of the partition plate 2 is provided with several stirring components. The stirring components include a second drive motor 30 fixedly connected to the bottom of the partition plate 2. The output shaft of the second drive motor 30 is fixedly connected to a vertical rod 31. Several stirring plates 32 are fixedly connected to the vertical rod 31. Several through holes are opened on the stirring plates 32.

[0045] In use, flocculants or alum, as well as chemical reagents with similar functions that can aggregate and precipitate particulate matter in wastewater, can be added to the first wastewater treatment tank 1. This causes the particulate matter in the wastewater to aggregate and precipitate. The second drive motor 30 controls the vertical rod 31 to rotate, thereby driving the stirring plate 32 to rotate. The stirring plate 32 stirs the wastewater at the bottom of the partition plate 2 and fully combines it with the flocculant. At the same time, the through holes on the stirring plate 32 cause a large number of bubbles to appear in the water during the rotation process, thereby carrying the lighter impurities to float to the upper layer of the water. Then, they are discharged through the drain hole 7 and enter the second wastewater treatment tank 6, where they undergo final filtration through the filter membrane of the second wastewater treatment tank 6.

[0046] In the description of this invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this invention, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0047] The embodiments described above are merely descriptions of preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Without departing from the spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by persons skilled in the art should fall within the scope of protection defined by the claims of the present invention.
